Table top spectrophotometer LTS-A11 is a high performance spectrophotometer with test caliber side ward for different aperture direction. Equipped with ETC technology solves the problem of long-term stability. The solid samples (paper sheets, cloth) can be placed directly on the measurement port & particles like pellets, tablets, powder (dye, food powder, chemical powder), paste (thick paste, opaque samples) can be placed in cube shape cells & then in the mouth of the measurement test.
